Programming languages like C and C++ have been used to write user space apps for decades. A language which can only be used for kernel space code is a niche within a niche within a niche. If Rust were only capable of that it would barely register on anyone's radar and be dead on arrival. In fact it's only recently that serious work was started on using Rust in a mainstream kernel (Linux); every project that Rust is known for is running in user space. People are confused about what system programming means and a lot of that confusion comes from parts of the Rust community which want to carve out a niche for Rust and keep claiming that Rust is particularly suited to system programming, as opposed to Go or D or other languages which are in reality also capable of tackling many system programming jobs, but have a garbage collector.
